THEODORE BURR, OF BATTLE CREEK, MICHIGAN, ASSIGNOR TO l-IIMSELF, AUGUSTUS ROWER, AND PARCEL BRINKERIIOFF,

LIFE-PRESERVING SHIP.

Speccation of Letters Patent No. 31,424, dated February 12, 1861.

To all whom it may concern.: v

Be it known that I, THEoDoRE BURR, of Battle Creek, in the county of Calhoun and State of Michigan, have invented a new and useful Improvement in Life-Preserving Ships; and I do hereby declare the following to be a full, clear, and exact description ot' the construction of the same, reference being had tothe annexed drawings, making a part of this speciiication, in which- Figure l is a perspective View. F 2 is the lower section of the mast being firmly secured to the hull and being so formed as to firmly t into a socket formed in that section of the mast which passes through the deck. Fig. 3 is a portion of the mast which passes through the deck and is provided with a socketso as to connect on the section below, to which it is secured by means or' a key passing through both sections.

The deck marked B, is constructed separate and apart from the hull, and yet when attached, to conform to the shape of the hull, in such a manner as to be made water tight, and by means of straps marked c,

irmly secured to the hull A, by means of l keys, the straps marked c being formed of metal and secured to the hull by a hinge joint, while the upper end is formed with a slot or slots through which the loop, or loops pass, sufficiently far to receive a key-pin which rmly secures the passenger or escape deck to the hull, and also provides the means whereby the deck can (in case of acc-ident, or otherwise, the hull becomes unseaworthy) be detached, so that in sinking the hull, the deck becomes a passenger ship, or boat with all the necessary conveniences for sailing.

I do not claim a saloon cabin or deck secured by bolts through the beams of a ship neither do I claim straps.

That I claim and desire to secure by Letters Patent ism The use of the socketed masts in connection with the life escape ship, detached by means of straps and keys substantially as described, and for the purpose set forth.

THECDORE BURR.
